Head Gasket Time...

Postby spookytooth » Tue Jun 24, 2014 8:58 pm



I've been having a puff of white smoke at startup out of the right bank for a while and figured the head gasket was on the way out. Tonight I took a short ride and when I pulled into the driveway the bike stalled (odd). I looked down and coolant was pouring out of the right-hand pipe. I removed the head and... it really doesn't look that bad? There's no obvious cracks or anything and... I was expecting to see one cylinder with a pristine shiny combustion chamber and piston but... they both looked well used with a bit of carbon buildup... odd.. and so the question...

Will any gl1000 head gasket work or are they year specific? Are right and left interchangeable?

Looking at the Honda fiche for my '76 and your '79, it shows the head gaskets for both years have the same part numbers and are also the same for both sides. Question: Why were you expecting one cylinder to be 'pristine'?

Usually when a head gasket is leaking coolant into a combustion chamber it literally steam cleans everything in that cylinder as it runs. Usually as soon as you pull the head you can tell which one by how clean it looks.

Dumb question... what would be a good tool to use to scrape the head gasket off without maring the head or case?

No dumb questions!

First, the obvious - spray-on gasket remover (let it sit for a while), and Scotchbrite sponges.

Putting a rubber wheel in a drill or other kind of spinny power tool can work as well.

You can try grinding a sharp bevel into the edge of a piece of plexiglas and using it as a chisel - no way plexiglas will mar aluminum.

Use Honda OEM gaskets, the price difference is not worth the risk. Most experts seem to think gasket sealer is not required with Honda OEM head gaskets.

I am the same stage. I have removed the head to replace the gasket. I purchased an OEM gasket and in my manual it says add sealant to both surfaces. I wanted to check in and see if sealant is necessary. If not, great! If so, what kind is recommended.

THanks!

I have heard copper spray sealant is fine, and may help for minor surface imperfection yet others report no trouble without it. The majority of experts say best to be OEM honda and dry with a good flat surface.
